Correct, the Procede doesn't modify the DME code in any way. In fact, the DME is completely ignorant of any tuning business. So physical removal leaves no evidence of tampering. Even if the black box data were to be analyzed by the powers that be.

As for "old technology" vs. "new technology", I think anyone suggesting that the Procede falls into the former camp may want to do some research. Flashes clearly have their place in the market. But like everything else, they do have their limitations.
